Chilling new video shows the moment tourists rushed to save the life of a Russian man who was shot by a deranged gunman atop one of the pyramids at Mexico’s Teotihuacán ruins.

The footage captures a woman providing water to the wounded tourist, Maikol Michelle Mitrocil, 42, who is lying on the ground after being shot Monday at the Pyramid of the Moon.

The unconscious victim’s lower left leg was soaked in blood, the video showed, as other people attempted to render aid.

Others touched the victim’s face, and implored him to speak.

“Miguel, come on, come on,” one woman could be heard frantically shouting.

“Miguel in the name of God,” she said in Spanish. “Please don’t die.”

In the background, someone can be heard shouting in English: “We need an ambulance.”

Several other stunned tourists could be seen sitting on the ground, comforting and hugging each other.

The shooter, who was identified as Julio César Jasso, 27, a native of the south-central Mexico state of Morelos, traveled from the Pacific coast state of Guerrero and arrived in Teotihuacán on April 8. He was staying at the Villa Meztli Hotel, where he reportedly plotted the assault, authorities said.

Jasso was seen on a separate video calmly pacing halfway up the 2,000-year-old pyramid, which was once used for ritual human sacrifice, before he placed a backpack on the ground around 11:30 a.m. and opened fire.

Jasso killed a Canadian tourist and wounded 13 other people, including 6-year-old Gerónimo González and his mother Dayana Castro, 37, who were visiting from Colombia.

Tourists attempted to seek cover from the gunshots by running down the uneven steps of the archeological site and leaping off them.

Jasso died of a self-inflicted gunshot wound on the scene, where security guards of the ancient grounds recovered a gun, knife and ammunition.

Jasso also had handwritten notes that reportedly reference the 1998 Columbine High School massacre, authorities said.
